Objective:
To explore the correlation and lag effects of environmental factors on pediatric respiratory disease visits at hospital, so as to provide scientific basis for disease prediction and optimizing clinical diagnosis and treatment.
Methods:
Data from 503 889 pediatric respiratory disease outpatient and emergency visits a central hospital in Minhang District of Shanghai between 2017 and 2019, along with concurrent meteorological data were collected. A distributed lag non-linear models (DLNM) was constructed to explore the specific relationship between pediatric respiratory disease consultations and various environmental factors and to quantify the cumulative lag effects of environmental factors on respiratory disease consultations.
Results:
Among the environmental factors, temperature, fine particulate matter (PM 2.5 ), inhalable particulate matter (PM 10 ), nitrogen dioxide (NO 2), and sulfur dioxide (SO 2) were associated with pediatric respiratory disease visits. After adjusting for temperature, PM 2.5 and PM 10 concentrations did not show significant immediate or lag effects. The relative risk (RR) of pediatric respiratory disease visits increased with rising NO 2 concentrations. When NO 2 concentration ≥55 μg/m 3, significant immediate and lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.05, 1.13, 1.17, and 1.21( P <0.05). The RR values showed an inverted “U” shaped relationship with SO 2 concentrations. When SO 2 concentration ≥5 μg/m 3, significant lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.03 , 1.03, and 1.04 ( P <0.05).
Conclusion
High concentrations of NO 2 and SO 2 increase the risk of pediatric respiratory disease visits, with observable lag effects.

Objective:
Neuronal apoptosis is considered to be a critical process in spinal cord injury (SCI). Despite growing evidence of the antiapoptotic, anti-inflammatory, and modulation of ischemic injury tolerance effects of extracellular ubiquitin (eUb), existing studies have paid less attention to the impact of eUb in neurological injury disorders, particularly in SCI. This study aimed to investigate whether eUb can play a protective role in neurons, both in vitro and in vivo, and explores the underlying mechanisms.
Methods:
By utilizing an oxygen glucose deprivation cellular model and a SCI rat model, we firstly investigated the therapeutic effects of eUb on SCI and further explored its effects on neuronal autophagy and mitochondria-dependent apoptosis-related indicators, as well as the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mechanical target of rapamycin (mTOR) signaling pathway.
Results:
In the SCI models both in vivo and in vitro, early intervention with eUb enhanced neuronal autophagy and inhibited mitochondrial apoptotic pathways, significantly mitigating SCI. Further studies had shown that this protective effect of eUb was mediated through its receptor, CXC chemokine receptor type 4 (CXCR4). Additionally, eUb-enhanced autophagy and antiapoptotic effects were possibly associated with inhibiting the PI3K/Akt/mTOR pathway.
Conclusion
In summary, the study demonstrates that early eUb intervention can enhance autophagy and inhibit mitochondrial apoptotic pathways via CXCR4, protecting neurons and promoting SCI repair.

Objective:To explore the clinical efficacy of areola approach endoscopic thyroidectomy (AET) and gasless axillary approach endoscopic thyroidectomy (GAET) in the treatment of papillary thyroid carcinoma (PTC) patients.Methods:A total of 96 PTC patients from the Thyroid Surgery Department of Linyi People’s Hospital from May. 2019 to May. 2022 were selected and randomly divided into 48 patients using a random number table method. The areola group received AET, while the armpit group received GAET. The surgical situation, postoperative recovery, relevant biochemical indicators [white blood cell count (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), parathyroid hormone (PTH), blood calcium] before and after surgery, postoperative pain level, discomfort level, neck function, and complications were compared between the two groups.Results:The surgical time and extubation time of the armpit group were (125.71±15.73) minutes and (3.12±0.53) days, respectively, which were shorter than those of the areola group (137.94±20.02) minutes and (3.48±0.46) days. The intraoperative bleeding volume was (14.19±4.16) mL, which was less than that of the areola group (22.65±7.39) mL, and the number of lymph nodes cleaned was 5.06±1.02, which was more than that of the areola group (4.23±1.14) ( P<0.05) ; there was no significant difference in postoperative drainage volume and hospital stay between the two groups ( P>0.05) ; Peripheral blood WBC in the armpit group on the 1st and 3rd day after surgery [ (5.69±0.15) ×10 9/L, (5.52±0.14) ] ×10 9/L, ESR [ (8.21±0.55) mm/h, (7.64±0.60) mm/h], CRP [ (10.06±1.78) ng/L, (8.93±1.33) ng/L] were lower than those in the areola group [ (5.83±0.21) ×10 9/L, (5.70±0.23) ×10 9/L, (8.87±0.74) mm/h, (8.19±0.68) mm/h, (12.45±1.90) ng/L, (10.45±1.50) ng/L] ( P<0.05). There was no significant difference in the levels of the above biochemical indicators 5 days after surgery ( P>0.05). There was no significant difference in peripheral blood PTH and calcium levels between the two groups on the 1st, 3rd, and 5th postoperative days ( P>0.05). The pain level [ (3.25±0.32) scores, (2.53±0.27) scores, (1.82±0.22) scores] and discomfort level [ (6.85±0.71) scores, (5.24±0.66) scores, (3.51±0.57) scores] in the axillary group were lower than those in the areola group [ (3.78±0.40) scores, (2.89±0.34) scores, (2.06±0.26) scores, (7.46±0.84) scores, (6.09±0.73) scores, (4.16±0.60) scores] on the 1st, 3rd, and 5th postoperative days ( P<0.05). The neck flexion, lateral flexion, and extension range of motion in the axillary group on the 3rd day after surgery were (33.16±3.09) °, (27.63±2.57) °, and (30.44 2.73) °, respectively, which were greater than those in the areola group[ (30.08±2.76) °, (25.14±2.30) °, and (27.98±2.54) °], and the swallowing disorder index was (30.16±4.97) points lower than the (34.83±4.13) points in the areola group ( P<0.05). The incidence of complications in the axillary group was 4.17% (2/48), lower than the 16.67% (8/48) in the areola group. Conclusion:GAET treatment for PTC patients can improve the effect of lymph node dissection, reduce the degree of surgical trauma, postoperative pain and discomfort, accelerate early postoperative recovery of neck function, and reduce complications.

Objective:
To investigate the effect of G protein-coupled receptor 108(GPR108) gene knockout on systemic inflammation in lipopolysaccharide(LPS)-induced sepsis mice.
Methods:
Male C57BL/6 mice and GPR108 gene knockout mice were randomly divided into 4 groups: WT group, WT-LPS group, KO group, KO-LPS group. The physiological characteristics of mice in different groups were observed, and the morphological changes of liver and lung tissues were observed. Macrophages were extracted from bone marrow and subjected to flow cytometry to detect their M1 polarization status. The expression levels of IL-6 in liver and lung tissues, macrophages, and serum were also measured.
Results:
KO-LPS group mice showed significant liver and lung tissue damage, with a significantly greater number of bone marrow-derived macrophages polarizing towards M1 in the KO-LPS group compared to the WT-LPS group. Additionally, at the tissue, cellular, and serum levels, the expression of IL-6 in the KO-LPS group mice was significantly higher than that in the WT-LPS group mice(P<0.05).
Conclusion
During the systemic inflammatory infection induced by LPS in mice, the lack of GPR108 exacerbates the systemic inflammatory response. GPR108 has an inhibitory effect on the inflammatory response in mice with LPS-induced sepsis.

Ischemic cerebrovascular disease(ICVD)refers to the degeneration,necrosis,or transient loss of function of local brain tissue due to blood supply disorders,and is one of the common neurological diseases.Exosomes are a subgroup of extracellular vesicles,characterized by good biocompatibility,low toxicity and immunogenicity,and strong designability.The components of exosomes include proteins,lipids,genetic materials,etc.They come from a wide range of sources and can be secreted by various cells under physiological or pathological conditions.The roles and related mechanisms of exosomes from different sources in the treatment of ICVD are different.This article reviews the therapeutic effects and related mechanisms of exesomes derived from mesenchymal stem cells,brain cells,blood,endothelial cells,and macrophages on ICVD,in order to provide reference for the clinical treatment of ICVD.
